NFC15 Datasheet, PDF (1/2 Pages) Artesyn Technologies – Single and dual output 15 Watt Wide input DC/DC converters

[ 2 YEAR WARRANTY ]
NFC15 SERIES
Single and dual output
• 4:1 input voltage range
• Low profile 0.46 inch
• 10.2 Watts/cubic inch
• 80% efficiency
• UL, CSA and VDE safety approvals
• Inhibit/sync function
• Overvoltage protection
• Fixed frequency operation
The NFC15 series of DC/DC converters are economical 15 Watt, hybrid DC/DC
converters that accept input voltages ranging from 20VDC to 72VDC. A
constant efficiency of 80% is maintained over the entire input voltage range.
The isolated floating output can be referenced as either positive or negative, or
stacked in series for higher output voltages. All models include current limited
outputs, overvoltage protection and remote on/off. Packaged in a low profile 2.0
x 1.6 x 0.46 inch case, the NFC15 is ideal for space critical applications in
telecommunications, data communications and distributed power networks.
